cation for Letters Patent filed of even date herewith.

Said chamber A is supported by two legs 17 secured to the base section 19 supplemented by a standard or post 18, a bracket 19 being bolted at 20 to said base 10 and having a split sleeve 21 surrounding the post or standard and secured thereto as by a bolt 22. Said legs 17 and standard 13 are preferably bolted to the floor or supporting structure.

Another bracket or head 23 has a split sleeve 24 surrounding the standard 18 adj acent the top thereto which is secured thereto by bolts or the like at 25. Integral with said sleeve 24 is a lug 26 which is overlapped by the aforesaid lug 15 and which is secured thereto by a removable bolt 27. Thus the chamber A is secured at different elevations and particularly adjacent the top and bottom, to the standard 18 which greatly rigidifies the construction and minimizes vibration and keeps it from turnin around by the motion of the parts therein or from falling or displacement of the machine in a storm on shipboard.

Operable within the chamberAis an agitating element 28 which may be of any desired form and, for example, of the type disclosed in the aforesaid applications Serial Numbers 387,472 and 387,47 3. Said base section 10 has a bearing sleeve 29 rising therefrom which supports or journals a vertical shaft 30 which is fastened at its upper end to a socket 31 of agitating member 28 so that it A casing 32 is bolted or otherwise fastened as at 33 against the under surface of base section 10 and is adapted to contain a bath of oil. Said casing 32 has a bearing portion 34 receiving the lower end of shaft 30 which provides for mounting a ball thrust bearing 35 on' which a worm wheel 36 rests and which is keyed to said shaft 30 and travels in the oil bath. In mesh with worm wheel 36 is a worm 37, also traveling in the said bath. Worm 37 is part of or integral with a shaft 38 which is suitably ournaled in thrust or other bearings 39 and 40, mounted by the casing 32.

Base section 10 has an enlargement at 41 to which a bearing bracket 42 is bolted as at 43, the same having a horizontal bearing 44 for the said shaft 38. A protective housing or casing tube 45 surrounds shaft 38, at one end fitting the stepped portion of bearing 40 and at the other end fitting a stepped portion. 46 of bracket bearing 44. Beyond said bearing 44, a bevel gear wheel 47 is keyed to shaft 38 and is arranged in mesh with another bevel gear wheel 48. These gear wheels 47 and 48 are preferably made of fiber so that they will operate practically noiselessly. Gear wheel 48 is keyed to a shaft 49, journale'd in an upright bearing sleeve 50 integral with the bracket 42. Shaft 49 at its upper end is coupled at 51 in any suitable manner to a driving motor 52, which is preferably an electric motor. Integral with the bracket 23 and projecting laterally therefrom, is a shelf 56. Bolted to the shelf 56 as at 57 is a housing section 58 which encloses the cow pling 51 and adjacent portions of the motor and shaft 49. A casing or protective sleeve 59 surrounds shaft 49, fitting a stepped portion 60 of bearing sleeve 50 and extending into the section 58. A. protective housing 60 of sectional form, is secured about the bevel gears 47 and 48, engaging adjacent portions of the bearing sleeve 50 and sleeve 44 for mounting. The sections of such housing 60 are detachably bolted or otherwise secured together as at 61. The bearings 44 and 50 may have oil cups 62 attached thereto so that the adjacent parts may be lubricated.

A guard plate 63 is bolted or fastened to the top of shelf 56 and has a central opening 64 which is occupied snugly by a guard ring 65. The ring 65 at the upper surface, intimately fits the adjacent portion of electric motor 52 and prevents water or moisture entering the section 58 or tube 59 and reaching the gears 47 and 48 or associated parts.

An oil cup 66 may be associated with ring 65 to lubricate the adjacent parts as shown in Figure 6. The electric motor 52 may be secured rigidly in place by bolts or the like 67 passed through the guard plate 63 and threaded to the motor casing.

Attention is called to the fact that the shaft 49 and associated parts are preferably arranged at an angle as shown in Figure 1, in order to better coact with the standard 13, in rigidifying or mounting the machine for operation substantially without vibration and also so as to give sufficient clearance for opening of the closure 12, although, if desired, such shaft 49 and associated parts, may be vertical.

As a result of the construction described, the chamber A is mounted so that it will operate practically without vibration and the gearing will operate substantially noiselessly. The motor 52 is located out of the range of water or moisture which may be used in or about the machine and the gears and different parts are protected so that water or moisture cannot reach or affect the same. At the same time, the electric motor support also forms a support for the machine and the motor itself is compactly disposed With respect to the machine and does not require additional floor space or room for its disposition and operation.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.
